LAGUARDIA COMMUNITY COLLEGE CITY UNIVERSITY OF NEW YORK DEPARTMENT OF MATHEMATICS, ENGINEERING AND COMPUTER SCIENCE MAT 117 – ALGEBRA AND TRIGONOMETRY 6 Lecture Hours, 1 Lab Hour, 3 Credits Prerequisite: MAT095 or placement (If you do not have the prerequisite, you may be removed from the course without notice.) CATALOG DESCRIPTION MAT117 comprises topics from both elementary and intermediate algebra and enables students requiring remedial MAT096 to earn college credit for MAT115 at the same time. All intermediate algebra topics are treated--polynomial, rational, exponential, logarithmic, and trigonometric expressions/functions in addition to basic right-triangle trigonometry. Rates of change and mathematical modeling are featured when appropriate. Instructional methods include lecture, guided groupwork and instructor feedback. PURPOSES AND GOALS MAT117 is designed to allow students who require MAT096 and college algebra to exit developmental mathematics and earn college credit within one semester. There will be strong emphasis on the conceptual aspects of algebra that underlie algebraic procedures. Because research shows that pedagogy is as important as curriculum for student success, instructors will employ a variety of instructional methods (e.g., lecture, guided groupwork, and graded/nongraded formative assessments/feedback). INSTRUCTIONAL OBJECTIVES 1. Enable students to improve their accuracy and fluency with the four fundamental arithmetic operations. 2. Introduce students to the concept of function and its application in modeling (linear and exponential cases in particular). 3. Familiarize students with the equivalence between the rate of change of a linear function and the (constant) slope of its graph, enabling students to graph straight line equations. 4. Introduce students to quadratic functions and their graphs, and enable them to find "zeroes" by solving quadratic equations. 5. Familiarize students with the arithmetic of rational expressions, reinforce the algebra required to solve equations involving rational expressions, and introduce rational functions. 6. Familiarize students with the arithmetic of radical expressions and provide them with algebraic methods for solving equations involving radicals. 7. Introduce students to exponential and (via the concept of inverse) logarithmic functions, and their graphs; additionally, provide students with the requisite computational and algebraic skills necessary to solve exponential and logarithmic equations. 8. Introduce students to right-triangle trigonometry, featuring the basic trigonometric ratios; and then familiarize them with the properties of the sine and cosine functions. PERFORMANCE OBJECTIVES 1. Add, subtract, multiply, and divide rational and decimal numbers with accuracy and fluency. 2. Explain and describe the functional concept/properties, and compare and contrast linear and exponential data. 3. Describe the equivalence of rate of change and slope for a linear function, and apply it in graphing straight lines. 4. Graph quadratic functions and solve quadratic equations. 5. Carry out arithmetic operations with rational expressions and solve equations involving them. 1|Page MAT 117 s yllabus Spring 2015 6. Carry out arithmetic operations with radical expressions and solve equations involving them. 7. Sketch graphs of exponential and logarithmic functions, and solve exponential and logarithmic equations. 8. Solve right-triangle trigonometry problems and sketch the graphs of the sine and cosine functions. Required Textbook: College Algebra (Special Edition for LaGuardia Community College) by Julie Miller, McGraw-Hill, 2015. Required Online Access: www.aleks.com. New copies of the required textbook contain an online access code. Evaluation: The purpose of a grading system is to give students, and those who will read their transcripts, an accurate record of their performance in this course. The role of the Mathematics, Engineering and Computer Science Department is to provide a fair, valid, and reliable structure for assessing student achievement. CATEGORY Online (Pie) Homework Quizzes Projects Instructor’s Tests Departmental Final Exam PERCENTAGE 10% 5% 10% 45% 30% EXPLANATION OF GRADING CATEGORIES Online (Pie) Homework: Students will work online on an “ALEKS pie” containing 12 course objectives. Each objective includes numerous topics. Credit will be earned for each mastered topic. Quizzes: Several short assessments will be administered throughout the semester. Projects: Your instructor will assign inquiry-learning projects throughout the semester (examples may be found at http://ctl.laguardia.edu/pql/sampler/). Instructor’s Tests: Your instructor will develop and administer three tests during the course of the semester. Departmental Final Exam: This two-hour written exam will be given during final examination week. It will be cumulative and cover all topics. PASSING GRADE POLICY In order to pass this course, you must have an average total score of at least 60% and no more than 12 hours of unexcused absences. ACADEMIC INTEGRITY This class will be conducted in compliance with LaGuardia Community College’s academic integrity policy. ATTENDANCE The maximum number of absences will be 12 hours. Unexcused absences beyond this maximum will result in a grade of WU or F. 2|Page MAT 117 s yllabus Spring 2015 COURSE OUTLINE Week Lesson 1-2 3 Week 1 4 5 6 7 8-9 Week 2 10 11 12-13 Week 3 14 15 16-21 Week 4 Opposite and Absolute Value, Arithmetic of Real Numbers (P.788) Area and Perimeter of Basic Figures and Compositions Thereof Inequalities and the Number Line – Interval and Set-Builder Notation (P.9) Positive Integer Exponents, Square and Cube Roots Order of Operations Algebraic Expressions, Simplifying, and Evaluating (P.24) Properties of Exponents (P.35) Scientific Notation Rational Exponents (P.49) Simplifying Radical Expressions (Square Root Only) Polynomials Polynomial Addition and Subtraction (P.63) Multiplication of Polynomials and Special Products Factoring Polynomials (P.76) 23-24 Rational Expressions, Simplifying and Multiplying (P.88) Adding and Subtracting Rational Expressions 25 Rationalizing the Denominator (Square Root Only) 26 Exam 1 22 3|Page Topic Section (Exercises) A2*(11-52) (P.799) Supplemental Materials R.1(41-72) (P.21) R.1(93-102) (P.22) R.1(103-116) (P.22) R.45-50 (P.32), 69-90 (P.33), 91-96) (P.33) R.3(13-70) (P.44) R.3(71-98) (P.45) R.4(27-54) (P.59) R.4(67-70(a) (P.60), 75-78, 83-84) R.5(15-22) (P.71) R.5(23-28) R.5(29-54) R.6(13-56,61) (P.85) R.7(15-42) (P.99) R.7(43-54) (P.100) R.7(71-72, 79-86) (P.101) MAT 117 s yllabus Spring 2015 Pie Homework Arithmetic Review Exponents/ Scientific Notn Radicals/ Ratl.
